Explore AMD to ESM migration #160416
Description
The VS Code project uses AMD (asynchronous module definition) which is somewhat of a pre-runner of native JS modules (ESM). AMD is mostly dead technology and we should migrate away from it. Our TypeScript sources are written with ESM imports/exports but we took a few dependencies on AMD as a "runtime" and we need to understand what it takes to move towards ESM.
High-level topics:
- we have a special AMD loader plugin that supports nls
- we also have a special plugin for CSS
- we have special bundle logic for both NLS and CSS dependencies
- we use
require.toUrlto locate sibling resources, like images, this needs to migrate ontoimport.meta.url
